SpectraPure® U.P.L.C. Ultra-Precise Level Controller II
Information

SpectraPure® Ultra-Precise ATO holds your tank's salinity constant while adding replacement water or Kalc in small doses. The pump can operate in either "fill mode" or "drain mode" when the water level changes. The Sensor Tube can be pre-set to operate with a minimal (0.1") change in water level up to a 4" difference. This calibration is saved even after a loss of power.

The ATO runs on a ten-second cycle. The pump can be on for any number of seconds each cycle, including zero (always off) and ten (always on). After the Ultra-Precise ATO is powered up, use the UP and DOWN buttons to adjust the ON-time in 10% steps. (This value is also saved even after a loss of power).

The pump used in the Ultra-Precise ATO is the same pump that is in the LiterMeter III™ , the leader in aquatic dosing for over 10 years. Now with our new improved, long life Peristaltic tubing. This is the quietist, most reliable Peristaltic Pump ever made.

Comments:I've had this unit running for over a year. The initial set of rollers wore out rather quickly. I was using kalk in my top off, and the tubing got clogged, setting the unit to run continuously without any liquid flowing. The manufacturer shipped me replacement rollers under warranty and it has been running perfectly ever since. Keeps the level in my sump (and as a result my salinity level) very precise. Although I switch off of dosing kalk and now use 2-part instead.

Great for any level

Comments:This is a really solid product it lasted for's at least four years free of any problems or any maintenance and it works awesomely. I've used the aqua med top off and it was constantly needing maintenance and upkeep. this really works exactly like you want to and to very precise. It's really easy to set up well. I'd recommend it to anyone who wants to keep the salinity level within very tight margin. I use it Kalk plus and it keeps my pH and salinity levels very even.

So far so good!
